Is tooth number 21 anterior or posterior?

Is tooth number 21 anterior or posterior?

Teeth Numbering: The upper teeth are numbered from 1-16 from right to left and the lower teeth are numbered 17-32 from left to right. Therefore, 1,16,17 and 32 would refer to your wisdom teeth and 6-11 and 22-26 would be your anterior teeth in the upper and lower jaws respectively.

What are proximal surfaces of teeth?

The surface of a tooth that is facing an adjacent tooth is referred to as a proximal surface. The area of the tooth that contacts the adjacent tooth is called the contact area [1].

What are the 5 surfaces of the anterior teeth?

Surfaces of the Teeth

  • Distal – The surface that is away from the midline of the face.
  • Facial – The surface that faces the cheeks or lips.
  • Incisal – The biting edge of an anterior tooth.
  • Lingual – The surface that faces the tongue.
  • Mesial – The surface that is closest to the midline of the face.

Where is tooth 24 and 25?

Teeth 23,24,25,26 are lower incisors. 24 and 25 are lower central incisors. 23 and 26 are lower lateral incisors. Teeth 6,11,22,27 are permanent cuspids or canines.

What is proximal surface?

proximal surface (proximate surface) the area where the mesial surface of one tooth touches the distal surface of another; called also contact area or surface.

Where is proximal surface?

The proximal surface lies next to another tooth. The tooth surfaces that face each other are called proximal surfaces. The proximal surface includes the entire length of the tooth from the crown to the root tip. Most mesial and distal surfaces are proximal surfaces.

What teeth are anterior?

Anterior teeth are the 12 teeth that make of up of maxillary and mandibular central incisors, lateral incisors, and canines (cuspids).

Where are the proximal and distal surfaces of teeth?

The proximal surface includes the entire length of the tooth from the crown to the root tip. Most mesial and distal surfaces are proximal surfaces. The mesial surface (toward the midline) contacts the tooth immediately anterior to it (mesial to it) in the dental arch.

What are the surfaces of teeth that face each other?

The tooth surfaces that face each other are called proximal surfaces. The proximal surface includes the entire length of the tooth from the crown to the root tip. Most mesial and distal surfaces are proximal surfaces. The mesial surface (toward the midline) contacts the tooth immediately anterior to it (mesial to it) in the dental arch.

Which is the biting edge of an anterior tooth?

Incisal – The biting edge of an anterior tooth. Lingual – The surface that faces the tongue. Mesial – The surface that is closest to the midline of the face. Occlusal – The chewing surface of posterior teeth.

Where is the mesial surface of a tooth?

Mesial. The mesial surface (toward the midline) contacts the tooth immediately anterior to it (mesial to it) in the dental arch. Following the curvature of the dental arch, it is the surface of a tooth that is closest to or facing the midline (or median line) of the arch.
